Purchased 2 arborvitae trees 3 mos. ago. Planted @ front of home, in full sun after 12 noon, in large pots. Trees approx. 6 ft. hi, diameter 2' to 2 1/2'. Watering @ 2 days. Exterior foliage is turning yellow; interior still shows much green. How do I bring back color, or are they dying? They seem to have turned yellow rather quickly in recent weeks. Have had much sun, but have watered every 2 days.

Hi there FredPhillip,
I’m Grow2girl from The Home Depot and welcome to the Community. Sorry to hear about your problem with the Arborvitae.
Once established, Arborvitae can thrive for years and years. But getting them established can be a challenge. Arborvitae is intended to be planted directly into the ground so they have the “earth” to pull water and nutrients from. Your Arborvitae is very large at 6 feet tall and my best suggestion is to relocate them into the ground away from your homes foundation. These plants grow best as privacy plants instead of focal plants in pots.
Now, I’m not sure where you live but at this time of year, I’m guessing it’s very hot. Transplanting them now may not be best idea. Let me give you a couple of options.
1. Leave them in the pots until the weather is cooler. Increase your watering to daily watering, if now twice a day, if you weather is in the 90’s and above. You may add an evergreen fertilizer to keep the plant healthy and increase new growth. Eventually, you will need to prune the yellow part of the shrub however this is done best in the fall.
2. Attempt to relocate them now by choosing an equally sunny location. Dig the hole in advance, making sure that it is 2 times the width as the root ball of the plant and as deep as the plants roots. Fill the hole with water before placing the plant in and let it drain. Add some peat moss to the hole (this helps with water retention and root development), place the shrub in the hole and fill with soil. They water thoroughly. You will need to water every day for several weeks to allow the roots to establish. Success is risky in the heat but it can be done. After a few weeks, you can begin to fertilize.
May I suggest an Alberta Spruce, as an alternative plant for your pots? This plant has a very similar look to the Arborvitae however it grows much slower and would be a better choice for your front door.
Please let us know if you have any additional questions and feel free to upload some photos if you need additional help. Good luck!
